1 Introduction
1.1 General Overview
The AS1100 is a long-distance sensor can measure targets with an accuracy of ± 3mm
(0.12 in) up to 100m (328 ft) away on natural targets and up to 150m (492 ft) away with
the aid of an Acuity reflective target. The AS1100 is a rugged laser sensor that can
accurately measure on difficult targets, including dark surfaces, surfaces in sunlight, and
glowing targets up to 1400°C. The maximum measurement frequency of the AS1100 is
100Hz in optimal conditions.
The AS1100 can communicate using RS-232, RS-422, or RS-485 serial protocols by
adjusting a single parameter. There is also a mini-USB connection under the back cover
that can be connected to a PC for easy configuration and troubleshooting. The AS1100
also comes with a current loop analog output with a user-configurable measurement
span that can output at a 4-20 mA or 0-20 mA current range.

2 Sensor Description
2.1 Principle of Operation
The AS1100 measures distance using a direct time-of-flight measurement of the laser
beam and a measurement of the phase shift between the beam as it exits and reenters
the sensor. In combination, this allows for precise measurements with targets at long
distances.
The laser beam leaves the sensor front through a small lens that is adjacent to the larger
main lens. The light reflects off the target then is collected through the main lens. The
light is then both measured to determine its time of flight and is compared to the
outgoing beam to determine the phase shift. This information is processed by the
sensor and the information communicated through serial and analog outputs accessed
through the cable connector, the screw terminals, or the mini-USB port.
2.2 Prohibited Use/Limits to Use
The AS1100 may not be used in any way contrary to this manual, in any way that may
jeopardize the safety of the user or others, or in any way contrary to local laws and
regulations.
2.2.1 Prohibited Actions
Prohibited actions include, but are not limited to:
Using the sensor without proper safety training.
Using outside of stated limits.
Deactivating of safety systems or removal of hazard labels.
Opening the sensor (Except the user removable back cover. See section
1.2)
Modifying the sensor internals or the main body of the sensor.
Aiming sensor directly into the sun.
Pointing the laser beam directly at 3rd parties or in areas where others
may be affected by the beam.
2.2.2 Environmental Limits
Do not use the AS1100 in the following environmental conditions:
Volatile or corrosive vapor or liquids (Salt, acid, poison, etc.)
Snow or rain (without an appropriate protective casing)
Radiation
Explosive environments
High-gloss (mirror-like) targets.
2.2.3 Application Limits
The AS1100 cannot be used in the following applications:
Aerospace (Aviation and Space Flight)
Nuclear technology
